When installing a child restraint sys-
tem
Observe the following when installing
child restraint system to the front passen-
ger seat if it is unavoidable. The front pas-
senger SRS air bag inflates with
considerable speed and force that if not
observed may lead to death or serious
injury to the child. ●
Never install a rear-facing child
restraint system on the front passenger
seat even if the “AIR BAG OFF” indi-
cator light is illuminated. In the event of
an accident, the force of the rapid infla-
tion of the front passenger airbag can
cause death or serious injury to the
child if the rear-fac ing child restraint
system is installed on the front passen-
ger seat. ●
A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable. A
child restraint system that requires a
top tether strap should not be used in
the front passenger seat since there is
no top tether strap anchor for the front
passenger seat. ●
A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, move the seat as far back as pos-
sible, and raise the seat to the upper
most position, even if the “AIR BAG
OFF” indicator light is illuminated. If
the head restraint interferes with the
child restraint system installation and
the head restraint can be removed,
remove the head restraint.
